Answer:
E=72000J or 72kj
Explanation:
The formula is E=pt you need to convert your t from minutes to seconds before proceeding
Answer:
27.1m/s
Explanation:
Given parameters:
Height of the building = 30m
Initial velocity = 12m/s
Unknown:
Final velocity = ?
Solution:
We apply one of the kinematics equation to solve this problem:
v² = u² + 2gh
v is the final velocity
u is the initial velocity
g is the acceleration due to gravity
h is the height
v² = 12² + (2 x 9.8 x 30)
v = 27.1m/s
In scientific inquiry, hypothesis acts as the road map that guide the researcher and show him how to go about his scientific investigation. Hypothesis provides a testable explanation for an observation and serves as the starting point for the scientific investigation.
Answer:
Solubility
Explanation:
Material becomes soluble in solvent and disappears.
Answer:
If both the maximum voltage and current are exceeded in a resistor, that the point will lie in the thermal breakdown of the resistor.
Explanation:
This indicated that there will be an abundance of free electrons which will be available freely. This abundance of the electrons in a conductor, will result in the reduction of the overall conductivity. whereas in an insulator or semiconductor this will enhance the overall conductivity.
As the point lies in the thermal breakdown, the Ohm's law is no longer valid and thus no analytical solution can be presented in this regard.
